Best TRV for physical clearance

Options

Hi, I have just fitted some tado TRV heads to my existing radiators. This is an old system and despite all the TRVs being Honeywell, one in particular physically touches the body of the radiator—it's more the rad than the valve to be honest.

In a month or so I am having all of my radiators replaced with new valves and I would like to know if anyone has any information on the TRVs that give the biggest physical clearance from the rad when mounted vertically. Or are they all the same?
